Chu kì: T\(_{ph\text{ú}t}\)= 60p=3600s
T \(gi\text{â}y\)=60s
T\(_{gi\text{ờ}}\)= 12h=43200s
Tần số góc: \(\omega_{gi\text{ờ}}=\dfrac{2\pi}{T_{gi\text{ờ}}}=\dfrac{2.3,14}{43200}=1,45\times10^{-4}\)(rad/s)
\(\omega_{ph\text{ú}t}=\dfrac{2\pi}{T_p}=0,0017\left(4\right)\)=1,74\(\times10^{-3}\)(rad/s)
\(\omega_{gi\text{â}y}=\dfrac{2\pi}{T_g}=0,104\left(6\right)\)(rad/s)
